We bought to use the radios just as a baby monitor. Nevertheless, I have also tried to work as far as the equipment. In the city I can say is more than 1 km, and if not so many houses are in between. As baby monitors are great, unfortunately my wife thinks that the devices to strong frequency have for our baby. No Idea. We have searched the internet long what each wrote about using the radios as a baby monitor. We have to use decided right baby monitor, but the radios sing really good to have to stay connected while driving with someone else. I can only recommend.
